一. 修改蓝牙名称:

system\bluetooth\data\main.conf !12

-Name = %m
+Name = LeaderUp

二. 修改蓝牙可被发现时间:

packages\apps\Settings\src\com\android\settings\bluetooth\RequestPermissionActivity.java !46

private static final int MAX_DISCOVERABLE_TIMEOUT = 300; //最大可发现时间

packages\apps\Settings\src\com\android\settings\bluetooth\BluetoothDiscoverableEnabler.java !42

/* package */  static final int DEFAULT_DISCOVERABLE_TIMEOUT = 120; //默认可发现时间
